The M12 is primarily used in a scouting capacity, or as an integral part of a mechanized infantry unit. In the case of the LRV and LAAV
variants it can hold three soldiers including the gunner. The mounted weapon includes a battery for short term operation separated from the vehicle, but normally operates on the vehicle’s power supply. The vehicle is powered by a 12 liter hydrogen-injected ICE and can reach speeds up to 125 kph (78 mph).
A number of variants of the Warthog are in service with UNSC forces, including the M831 TT
(which eliminates the support weapon in favor of four side-facing passenger seats), the M864 A (with an enclosed passenger compartment and treads in place of wheels), and the M914 RV (equipped with a towing winch and a heavy duty motor and gear system).
